Another way to use Fortran in GNU Radio is to wrap them in a C++ block,
you might want to have a look at [0] to see how we did that. This
however supposes that you actually want to use the GNU Radio runtime to
write a GNU Radio application (which I'm not entirely sure of is what
you want to do). Maybe you could elaborate further on what you are
actually planning to do?

If I understand you correctly you want to have an answer on how
efficient that is and if it is possible to do this *without*
understanding the blocks?!

I think there is no official convention for writing Fortran blocks in
GNU Radio, but for coding guidelines see README.hacking.
May I ask a final question, why did you select Fortran? Do you have a
lot of matrix computations to do?
In our case we used Fortran for several reasons including wanting to
learn how to do it, and (to our knowledge) the lack of equally fast
implementations in C/C++ of the matrix computations involved.
Cheers & happy hacking,
